Grodan Macro Plugs with Slit 1.5" (Bag of 50)

This is the growing media that is best used with our patented cup design.

The rockwool plugs absorb water which allows the seed to germinate without the need of transplanting. This means to regrow your plants costs 45 cents instead of 4-5 $ a plant.

If you plan on transplanting your garden to soil, we recommend using hemp plugs and not rockwool. Hemp will bio-degrade much faster.
